`x^3+5x^2+2x-8`

Divide 2x^(3) - 5x^(2) - 8x + 15 by x - 3.

Add the following expressions: (i) 8a-6a b+5b ,\ -6a-a b-8b\ a n d-4a+2a b+3b (ii) 5x^3+7+6x-5x^2,\ 2x^2-8-9x ,\ 4x-2x^2+3x^3,\ 3x^3-9x-x^2\ a n d\ x-x^2-x^3-4

Add the following expressions: (i) 8a-6a b+5b ,\ -6a-a b-8b\ a n d-4a+2a b+3b (ii) 5x^3+7+6x-5x^2,\ 2x^2-8-9x ,\ 4x-2x^2+3x^3,\ 3x^3-9x-x^2\ a n d\ x-x^2-x^3-4

Divide 3x^(4)-5x^(3)-2x^2-8x+3 by x^(2)+5x+3

Simplify : 15x-[8x^2 + 3x^2 - {8x^2 - (4-2x-x^3)-5x^3}-2x]

Divide 2x^(3)-5x^(2)-8x+15 by x-3.

Add: 5x^(2) + 3x - 8, 4x + 7 - 2x^(2) and 6 - 5x + 4x^(2)

Add: 5x^(2) - 7x + 3, -8x^(2) + 2x -5 and 7x^(2) - x - 2
